php - using API to UK live rail departure boards

[dbrb2]

Hello - I wonder if someone can give a bit of adice. I came across the API to the UK live train departure boards recently - although I understand it has been around for a while. The interface is described here:

http://www.livedepartureboards.co.uk/ldbws/

As my first attempt at retreiving some info using it, I used the following bit of php:

<?
require_once 'SOAP/Client.php';

$wsdl_url = '[URL unfurl="true"]http://realtime.nationalrail.co.uk/ldbws/wsdl.aspx';[/URL]
$wsdl = new SOAP_WSDL($wsdl_url);
$proxy=$wsdl->getProxy();

$response =  $proxy->GetDepartureBoard(10,'KGX');

print_r($response);
?>

I have tried various permutations on the above, but continuously get the error "No crs code required" (where crs code is the three digit station code)

Any ideas?

Cheers,

Ben

That's not the PHP5 SOAP interface is it ?, might be worth using that (assuming your on 5) and see what comes out.

No - I was using the PEAR soap library for php since it works in older versions of php. As it turns out I am running php 5, so I tried it using the native soap client support, but unfortunately got exactly the same error returned :-(

<?php
$client = new SoapClient("[URL unfurl="true"]http://realtime.nationalrail.co.uk/ldbws/wsdl.aspx");[/URL]

try{
        $data=$client->GetDepartureBoard(10,"KGX");
}
catch (SoapFault $exception){
        echo 'EXCEPTION='.$exception;
}
print_r($data);
?>

Ah...

Well, the my initial attempt using PEAR didn't work, and neither did my first attempt at using native php support.

But passing the parameters in using an array worked fine:

[/code]
<?php
$client = new SoapClient("

http://realtime.nationalrail.co.uk/ldbws/wsdl.aspx");

$arr = array("crs" => "KGX", "numRows" => 10);

$data=$client->GetDepartureBoard($arr);

print_r($data);
?>
[/code]

Hpowever, using the same fix with thr PEAR library still gave the original error. At least it is working in php 5 now though

i think that there may have been an issue with the server. when the question was first posted I was unable to access the server to retrieve the SOAP methods exposed by the API.

Glad you got it to work, SOAP is supposed to be easy - it never is !
